A keyboard having keys arranged thereon and large-sized characters each of which is continuously given over a top surface and a front surface of each key to be easily seen so that movements between a first line of sight on the keys and a second line of sight on a monitor are reduced to a minimum. A character may be placed on a plane under a transparent layer in a key to be seen through the transparent part. A key seal includes upper and front parts to be attached to top and front surfaces of a key.
